One of the best features in Firefox is one of its least-known. Many, many people complain of Firefox feeling slow and bloated over time, and in a number of cases, they’re not wrong. They just don’t know that surfing the web can be analogous to playing Katamari Damacy, where simply browsing can accumulate cruft until you have this big ball of metadata that slows you down.
If you find your Firefox experience is sub-par and a little more pokey than you’d like, you should try resetting your profile before moving over to another product. You should know that your preferences, extensions, and themes will be reset/removed, but since you’re planning on installing Chrome or another browser, I’m willing to bet that’s ok (and you should back your profile up before you do this, just in case). Your browsing history, bookmarks, and form info will be saved, and that’s the important thing.
To reset your profile, open up Help->Troubleshooting Information from the Help menu, and click the reset button. This simple procedure will cure most things that ail you performance-wise with Firefox. You should also read our support article on Resetting Your Firefox Profile, which will give you the the full scoop on what happens when you click.
There, doesn’t that feel better?
